2025 Toyota Grand Highlander Owner Complaints

The Panoramic Roof Glass shattered on its own while driving on the freeway, there were no overpasses, no trees, no semi-trucks, no other vehicle in front of me while i was driving. The shattered glass pieces fell on my children in the back seats luckily there were no injuries as we closed the screen immediately.

When going over rough or uneven roads, the car produces a strong low-frequency resonance, like a bass-heavy "boom". This causes a very uncomfortable feeling of pressure changing in my ears, gives me a headache and ear pain whenever I drive in local roads, which is the majority of driving in my area. This causes me to need to pull over and stop the car frequently to readjust my hearing. I've found many reports from others of the same issue but Toyota have not acknowledged it or found a solution.

I am submitting this complaint regarding a serious safety hazard and design flaw with the 2025 Toyota Grand Highlander Hybrid. While driving on a two-lane highway, our vehicle suddenly lost power and warning lights appeared on the dashboard. We were forced to exit the highway immediately (we were less than 0.5 miles to an exit). Shortly after pulling onto the off-ramp, the vehicle entered limp mode, significantly limiting its ability to function - all assist systems deactivated amd the car has a significant decrease in power. We were able to drive approximately half a mile to a nearby gas station, where we called for a tow. This situation left us vulnerable on a busy roadway, placing both us and other drivers at risk. The Toyota dealership diagnosed the issue as damage to the hybrid inverter radiator, allegedly caused by a rock or piece of debris entering through the front grille. We were told this was not covered under warranty, and to make matters worse, the necessary part is currently on backorder for three weeks to three months—leaving the vehicle undriveable. A significant concern is the design of the front grille, which has large, open gaps that allow ordinary road debris to enter the engine compartment. This leaves critical components like the hybrid inverter radiator exposed and vulnerable, even under standard driving conditions. After researching, I discovered numerous similar reports from other Toyota hybrid owners—including those with Grand Highlanders, Highlander Hybrids, RAV4 Hybrids, and Prius models—who have experienced the exact same issue. In nearly every case, drivers were told it was due to external damage and denied warranty coverage. This presents a clear and growing safety issue: 1. Sudden power loss on a highway or arterial road increases the risk of collision. 2. A critical hybrid system component is inadequately

The vehicle was in PARK and the IGN was in the ON/RUN position and the air conditioning was on. There was no one in the driver's seat but there was an occupant sitting buckled in the front passenger seat. The passenger heard a sound (possibly the ICE turning on) and he felt the vehicle move forward about five inches. He became worried about his safety and pressed the IGN button in order to turn the vehicle off. It could have pushed itself into other cars in the parking lot or pedestrians. A report was made to the local police department on the same day. This occurred in a retail parking lot. Video footage cannot be obtained as a police officer or insurance company must request it. I have not seen a check engine light nor any message prompts and it has not been inspected by a dealership.

Fuel fill-ups averaging 13-14 gallons when vehicle trip computer alerts 0 miles remaining distance to empty. Fuel tank capacity published as 17.8 gallons. Total vehicle range understated, requiring more frequent stops at gas stations to fill. Not a direct safety concern, but a significant nuisance and dealer has stated this is normal and there is no fix for this issue. EPA estimated MPG 26-27, should equate to approximately 460+ miles/tank. Instead experiencing approximately 350-365 miles per full tank of fuel.

I am writing to report a serious issue with my 2025 Toyota Grand Highlander Hybrid (VIN: [XXX] ), purchased on [XXX] from Hillside Toyota . I have noticed water leaking from the top of the windshield, dripping onto the steering wheel and dashboard, particularly during rain or after a car wash. This issue began on [XXX] and I saw couple of times under these conditions, posing a potential safety hazard due to driver distraction and possible damage to electrical components. I have taken the vehicle to Hillside Toyota on 05/05/25 and 07/21/25 where they inspected the vehicle but could not identify the source of the leak” or “attempted a repair, but the issue persists. This issue is concerning, as it affects the safety and functionality of my vehicle, which has only 1184 miles INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Inconsistently but on numerous occasions, this vehicle has experienced harsh shifting, hesitation, or jerking during low-speed acceleration (e.g., 20-40 mph) or gear engagement. This was a known and reported issue with the 2024 model for which Toyota provided a fix. They have not provided one for the 2025 models. This issue is a safety risk while driving because with the surge you feel you must quickly let off the pedal, and with the hesitation you let off the brake indicating you will move forward yet the vehicle doesn’t accelerate.

The 2024 and 2025 Toyota Grand Highlander has excessive hood shaking and vibration at the rear of the vehicle. It is directly under the projection area of the windshield and directs your attention to the movement. At highway speeds the shaking is excessive. Toyota has not been able to find a repair for this issue.

Hood on 2025 Toyota Grand Highlander vibrates/flutters due to poorly designed aluminum construction. Very distracting and causes drivers to take eyes off the road. Toyota has issued T-SB-0111-24 for the 2024 Grand Highlander for this specific issue but my dealership told me that it doesn't apply to the 2025 but the hood part number is the same for both years. The constant vibration could eventually "work harden" the thin metal and ultimatlly allow the hood to break off the vehicle. Check out the old Jimmy Stewart movie when the constant vibration made the tail break off the airplane.

Missing the wire connector for the puddle lamp installation? although not a safety issue, would like to bring this to attention; wire connectors (and wires) missing on both driver and passenger doors? Not sure if this was a factory oversight, or an error in original wiring diagram of Toyota? If so, there could be other wires missing in the vehicle as well. Hopefully Toyota will look into this and propose a fix for their customers. Thank you
